半导体设备. 第5-6部分: 光电设备. 发光二极管

[中文适用范围]： IEC 60747的这一部分规定了用于信号、控制器、传感器等一般工业应用的发光二极管(LED)的术语、基本额定值和特性、测量方法和质量评估。 [外文原描述]： IEC 60747-5-6:2021 specifies the terminology, the essential ratings and characteristics, the measuring methods and the quality evaluations of light emitting diodes (LEDs) for general industrial applications such as signals, controllers, sensors, etc. LEDs for lighting applications are out of the scope of this part of IEC 60747. LEDs are classified as follows: - LED package; - LED flat illuminator; - LED numeric display and alpha-numeric display; - LED dot-matrix display; - infrared-emitting diode (IR LED); - ultraviolet-emitting diode (UV LED). LEDs with a heat spreader or having a terminal geometry that performs the function of a heat spreader are within the scope of this part of IEC 60747. An integration of LEDs and controlgears, integrated LED modules, semi-integrated LED modules, integrated LED lamps or semi-integrated LED lamps, are out of the scope of this part of IEC 60747. This edition includes the following significant technical changes with respect to the previous edition: - ultraviolet-emitting diodes (UV LED) and their related technical contents were added; - power efficiency (ηPE) as part of electrical and optical characteristics were added; - new measuring methods related to thermal resistance were added; - hydrogen sulphide corrosion test was added to quality evaluation; - some standards were added to the bibliography.
